Society for Creative Anachronism. Fun group in all states. Been around forever, except in my area. Lol. 

 OK cool, they say it's a sport, more than re-enactment.  

 society for creative anachronism

The SCA community includes over 30,000 members in 20 kingdoms around the globe. Our participants learn about the arts, skills, and culture of the Middle Ages and Renaissance in an atmosphere of fun, through tournaments, royal courts, feasts, dancing, classes, hands-on workshops, and more 

 There may have been some of them there. Lots of other groups doing Viking/Saxon re-enactment with little villages set up,  cooking, chainmail making etc
